-Be it known that I, VINToN E. SIssoN, a

ycari' with the roof boards,

"citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new'and useful Improvements'in Met-al Reenforcements forthe -Wooden End NV all of a lRail- 'way'BoX- Car,= of -which the following is a specification.l *My invention Arelates to the reenforcement ofthe wooden end walls of railway bolt cars, either at' the time the cars are 'built'y or subsequently in the repair of the sa1ne;a1id' the-invention isl concerned especially with the improvements, in certain important respects, of the type of end reenforc'ement' 'now' in common use which coniprises 'a' pair of' Vertical' or substantially vertical metal members," Z-bars, for example, on the outside ofthe car, usually aligned withv the wooden intermediate end posts of the ca'r" fra-1ning,and' a bracing structure on the inside of the car lto which the vertical reinforcing members are attached t-hroi'igh the end plate, which interior'bracing struclture by its connect-ion through the employment of diagonally extending struts vor bracesrunning to the side walls'of the car, serves to transmit the' stresses on the vertical members to the-side walls of the' car and fwith the vertical members tends to keep the superstructure of the 'car 'from the-'destructive stra-ins and distortions'lnown as weav- .ing`. l

One of the object's'of'my present invention is to provide a more rigid and secure anchorage ofthe vertical reinforcing members tothe end plate brace, as this portion of the interior reinforcing structurema'y be called, and to4 strengthen thel latt'er ele'- ment atthe place wherey strength is'v espej cially required, to-wit, atthe middle ofthe car. i

A further Objectis to simplify and malte .l more convenient and economical the manufacture of' the end plate brace bly inl the car'.` l

The invention consists of the new andimproved arrangements, lc mstructions and devices shown in the drawings and to be hereinafter described an claimed for carrying out lthe above stated obje/cts and suchfot'her incident-al objects as will appear in the following description of the preferred embodivlment" of the invention. f'

and its assem- `struction f :In the drawings, i Fig; 1is a plan view of the end ofy the ridge pole and purlins removed.y Fig. 2-is a fragmentaiyend elevation `of the upper partof the car with thelwooden end wall broken away .to illustrate'the conthe .interior relnforcmg structure.

Fig.' 3 isa persective of a detail showing the connection of one of the bracing mem- `like parts `'in the several` figures of 'the drawings.

Referring .to the drawings, designates the outer sheathing of the end wall, 11 the side sheathing,`12 the roof, 13 lthe end plate, 14. A14 the side plates .and 15, i5 the intermediate end posts. The car structure as described is of familiar type. On the` o-ut-side ofy the end wall are arranged a pair a"of substantiallyupright, preferably vertical bracing lmembers 16, aligned with the intermediate endf'posts 15 yto `which they are secured by' bolts 17 through the outer sheathing, these endwall reenforce-ments being 4preferably in the form 'of Z-bars Aas shown.

l/Vithin' the car is a transversely arranged -end plate brace which consists, inthe preferred embodiment of my invention, of a pairfofangle bars 18, 419 arranged so that they overlap for a distance al trifle greater than the distance between the Z-bars 16. rIhe member 18has its Vertical flange 20 projecting upwardly froml its horizontal fiangel 21 while the member19 has its vertical flange 22 projecting downwardly from its horizontal flange 23. The vertical flanges Vlie fatwise against the inner surface ofthe end plate 13' and are secured thereto by bolts' 9A. The horizonta-lfianges of' members '18' and 19 project inwardly and are spaced apart to receive the ends' of the diagonal bracing members 25, 25 which intersect' andare 'secured together at such `intersection by aplate 2(5,the diagonal braces being secured to the horizontal flanges 21, 23 by rivets 27, or other suitable fastening devices.l"`Preferably 'the' flanges 2l', 23 are riveted together', as shown at 28, with the interposition of a` spacing plate :29 at a place ymidway of the overlap of members 18 and l 19. The other extremities of the diagonal braces 25 are riveted to brackets 30, which latterk are secured by bolts 31, or other suitable fastening devices, to the side plates 14 of the car. The upper extremities of the Z-bars 16 are bolted, or otherwise secured, in each case, to each of the two members 18 and 19 of the end plate brace, as shown at 32, 33. The end plate brace is designed to extend, preferably, across the end plate from side to side of the car and.is secure-d at both ends to the side walls of the car. The most desirable way of making this connect-iony is to bend the end of each of the members 18 and 19, as

.shown in Fig. 1 to provide a diagonal strut- 34 to extend across the corner of the car and an end portion 35 which lies against the side plate and may be secured thereto by bolts 36.

Any suitable means may be employed for securing the lower ends of the Z-bars 16 to the under frame of the car.

Certain important advantages are obtained by making the end plate brace 18, 19 in two sections arranged and connected with the other parts of the reinforcing structure as shown and described. If the end plate brace be made in one piece: some difficulty is experienced in bending the ends to make the attachment to the side walls of the car, which is desirable in order to utilize the end plate brace to rigidify the car structure against weaving, due to the tendency of the metal to shrink somewhat and become distorted with the changes in temperature `incident to the bending operation. Moreover, by makingthe brace in two parts and overlapping the parts at the middle the brace is given great strength where strength is necessary, that is, at the center of the ear. Besides this it is possible to obtain a very strong and rigid anchorage of thel upper ends of the Z-bars, which form. the exterior portion of the reinforcing structure, to the interior reenforcement. Two bolts can be used in each ease, one a considerable distance above the other, one bolt attaching theZ-bar to one of the members of the end plate brace and the other to the other member. Reinforcing structures of this general character have two functions to perform. In the first place, they strengthen the end wall of the car against the thrusts and pressures of shifting cargoes. In such case the stresses againstthe outside reenforcement, consisting of Z-bars, are transmitted to the inner reinforcing structure and by it to the sides of the car. It is important. therefore, that the anchorage between the exterior and interior reenforcetion of the reenforcement is to brace the car superstructure against the 'various diagonal distortions known as weaving to which railway box cars are subjected, due to the inert-ia of the upper port-ion of the car and thel tendency of the car body te swing sidewise in roundingcurves or going over rough track.l In the performance of this function of the reenforcement it is equally important that rigidity be maintained between the outer and interior reinforcingl structures in 4order that they may cooperate to keepthe elements of the car framing r`in line.

In Figj I have illustrated a modified formr ofend plate brace formed of a plurality of parts for the purpose above described and providing an extended surface for the`Ivl attachment of the outer vertical braces 16. This form of end plate brace comprises a pair of angle members 37 each extending toward the center of the car to a lpoint beyond the point of attachment of the vertical'` bracing members 16. yThese angle members are secured together to form a rigid unit by means of an intermediate section 38 of angle iron to which the members 37 are riveted as will be hereinafter described. The yangle ymember 38 is made of a length sufiicient to extend beyond the points of attachment of the vertical bracing members 16 so as to overlap the'members 37 and provide an-extended surface as in the caseof the form previously described for the attachment of the upper ends. of the bracing members 16. Such extended attaching surface consists of the upwardly extending vertical flange 39 of the member 38 and the downwardly extending flanges 40 o-f the members 37. The diagonal bracing members 41 have the same general construction as those previously described and are. connected to the end plate brace at the regions where the members 38 and 37 overlap by means of rivets or other suitable fastenings 42 which pass through the members 41 and the. liori zontal flanges of the members 37 and 38. The rivets 42 thus secure the braces 41 to the end-plate brace and the members 37 to the member 38. The braces 41 are riveted at the region oftheir intersection to a plate 43, placed between the same, by means of rivets 44. It will be noted that the upper brace 41 is secured to the upper. surface of the horizontal flange of the member 3S and the lower brace 41 to the lower surface of the horizontal flange ofone 0f the members 37. The other vextremities of the brac-es 41 are connected to the side plates bly means of brackets 45vand suitable rivets and bolts in the manner already described in connection with the construction illustrated in Figs. 1 to 4 inclusive.

l The form of construction shown in Fig. 5 reduces the difficulties of manufacture as described in connection with theY form of Cil brace 'shownin' Fig. 4; and also provides the v extended surface forthe' attac-limeiit of the outer bracing'member 16.v`
